Web Service Sample

09/01/2009

This sample demonstrates how to invoke Web services from a workflow and also how to publish a workflow as a Web service.

Specifically this sample demonstrates the use of the following activities:

The solution consists of three workflow projects. WebServicePublish and WebServicePublish_WebService are a workflow that is published as a Web service, and WebServiceInvoke is a sequential workflow that invokes the workflow that is published as a Web service.

Note

To publish a workflow as a Web service, right-click the project that contains the workflow and select Publish as a Web Service. The project must be a workflow project, and it must have at least one workflow that contains the WebServiceReceiveActivity and WebServiceOutputActivity activities.

The workflow that invokes the Web service sends a purchase order ID. The Web service prefixes the string "Approved" to the ID and sends it back as a response.

Note

To build and run the sample, you must install the ASP.NET 2.0 Development Server that is included with Visual Studio 2005 or Visual Web Developer 2005 Express Edition.
